Only on firefox, the music on apple music keeps changing volume. I can hear it sound fine for a second but then it changes the volume to around half of what its meant to be. I dont see any settings to change it, its fine on other browsers, im genuinely unsure of what to do.

There is an issue with MKV video playback with MP3 audio track in FireFox. The problem is that MKV video plays MP3 audio track without any sound. With AAC audio track the problem is that MKV video initially downloads whole video and only then plays it. In comparison with MP3 and AAC the benefit of MP3 is much better quality and it starts playing without downloading whole video like MP4.

It would be nice if you add support MKV video with MP3 audio playback.

When watching a video on a platform and the video needs to load, instead of pausing to load then play it once again, it doesn't stop, making the video audio sound so glitchy that you can't understand it

surprisingly, it works as expected on youtube

The last two days my internet performed poorly, but it worked (in between crashes). Now it took me 12 computer restarts and hours of patience to get to this page and plead for any sort of internet. I can't visit any page with moving imagery or it will crash, it won't start any video if there would be sound on it, stating that I don't have permission or simply not doing anything at all. I can't even finish the news-program I was watching on public acces tv. Please fix this!!! I'm desperate! I need to watch instructions for school and see my work-roster and I can not acces any of those pages anymore.

Since I updated to Firefox 141.02 I have not been able to play videos on Paramount+ or Netflix. I get an error on the top that says the Widevine plugin has crashed on both streaming services. I have checked that the plugin is on and there are no updates. I am on Ubuntu 24.04. Video on YouTube plays as normal

For a couple of days now Instagram linked videos won't play here. Actually some of them will -- my own reels and anything linked with that button that looks like a movie 'clapper'. But videos that show the triangular arrow pointing to the right, nothing happens when you click. Not sure if this is a FF issue or maybe something changed at Instagram. Did a google search and nothing came up.

I had a new computer installed. The output from the speakers is almost inaudible in Firefox, but it's better on other browsers. The tech said that it's a Firefox issue, not a speaker issue--she said the speakers are OK.

Recently I had a problem with Firefox opening a second icon on my Macbook. In order to fix it, I uninstalled and then re-downloaded Firefox. I tried to put everything back to the way it was before but I still have a problem with some websites not playing video. Most notably, Instagram and Blue Sky. I have attached screen shots. I have set Firefox to playback videos automatically but this has had no affect. Can anyone help?

Hello, I have a MAC computer. For some reason, when FIREFOX made its newest update, I can no longer watch videos on YouTube. The video will start but then give me the death circle, and it will not come out of it unless I click just a slight distance away on the timeline of the video. Then, the video will go for about 20 seconds and do the same thing. I continually have to click on the timeline in front of where it stopped when the video stops, and then it will give me about 20 more seconds of the video before the white arrow circle shows up again. You can wait all day for the circle, but it will not start again unless you click on the timeline again ahead of where it froze.

Hello, I am currently using windows 11 with firefox 149.0. Regardless of what website I use (youtube. steam etc), the browser struggles to establish consistent connection to my bluetooth earbuds. It connects for one moment, but then soon the volume goes out and eventually it disconnects. Though it would reconnect soon, the cycle just keeps ongoing. I have experimented with other apps and browsers, as well as multiple bluetooth earbuds of other brands to be sure that it is a firefox issue. I have checked the volume mixer menu to ensure that there is nothing wrong. I have also made sure that my drivers are all up to date with no issue. But the issue still persists.

Videos in YouTube play at about 50% brightness in full screen and not full screen, unless hardware acceleration is turned off, my mouse is hovering over an auto play thumbnail, or when the video is not in full screen and I open the right click context menu on the video.

I have an AW3225QF HDR monitor and an RTX 5070ti
